Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a page management system for a printing system used in an electronic computer system or the like.

[0002]

2. Description of the Related Art FIG. 2 is a schematic block diagram showing a conventional printing system. In the figure, reference numeral 21 denotes print data stored in an information recording medium such as a magnetic disk, and reference numeral 22 denotes print data output means for taking out the print data in predetermined block units. The print data extracted by the print data output unit 22 is printed for each block by the print trial unit 2
5, the print trial means 25 performs a print simulation for each block of the passed print data.
If, as a result of the print simulation, it is determined that the page will be changed, the print trial means 25
Informs the print data output means 22 of that fact.

When the print data output means 22 is notified of the occurrence of a page change, the block position of the page in the print data 21 of the block is checked, and the page number of the page to which the block belongs and the block thereof. The position of is stored. When this process ends, the print data of one block of the print data output means 22 is passed to the printing device 23, and the printing device 23 edits the print data of the block and prints.

If printing is interrupted due to a failure of the printing device 23 during printing and it becomes difficult to continue printing, the print data output means 22 uses the print instructing means 24 to print to the user. Is notified, and at the same time the reprint start page is asked. Therefore, when the user instructs the reprint start page by the print instructing means 24 after the failure is recovered, the print data output means 22 causes the print data output means 22 to correspond to the page number previously stored and the leading block of the page. The position of the first block of the reprint start page is checked by referring to. Then, the print data is sequentially transferred to the printing device 23 from the obtained first block, and the printing is restarted. When printing is interrupted in this way, printing is performed from the designated reprint start page.

[0005]

However, in the above-mentioned conventional printing system, since the page separation is obtained by performing the print simulation for each predetermined block unit of the print data, the print data becomes complicated and a large amount of data is generated. However, there is a problem that the processing time increases accordingly. Further, since it is necessary to perform the same processing as that of the printing apparatus in order to perform the printing simulation, it is necessary to add the same function to the printing simulation when adding a function to the printing apparatus, which doubles the system development cost. There was a problem of becoming. Further, when the printing is restarted after the failure recovery, if the reprint start page specified by the user is the back side, the reprint is performed from the back page as it is. There was a problem that the page became meaningless.

The present invention has been made to solve the above problems, and effectively prevents an increase in processing time and development cost, and at the time of reprinting, printing is started from the back page. It is an object of the present invention to provide a page management method for a printing system, which enables efficient page management without any problems.

[0007]

In order to achieve the above object, the present invention has means for fetching print data in a predetermined block unit, and editing for each print data of a predetermined block fetched by this means. Means for performing printing,
A means for returning the position in the block of the code that caused the page change obtained in the process of editing this printing means and the page number to which the print data after that code belongs,
A means for checking the block position of the head block of the page based on the returned information, and storing the obtained block position information of the head block together with the page information as page management information. When the printing means suspends the printing and restarts the printing, it is designated by checking the position of the head code of the designated reprint start page based on the page management information. It is characterized in that printing is started from the print data at the head of the page.

[0008]

According to the present invention, the page information obtained in the process of editing the print data by the printing means for each predetermined block unit, that is, the position in the block of the code that caused the page break and the print data after the code. The page number to which the item belongs is returned, the position of the first block of the page is checked based on this information, and it is stored as page management information together with the page number. When printing is interrupted due to a failure of the printing means, and when the failure is recovered and printing is resumed, by checking the position of the head code of the reprint start page specified based on the page management information, Start printing from the print data at the beginning of the specified page. Therefore, the start position of the print data of the reprint start page is obtained by checking based on the page information at the time of editing the printing means instead of performing the print simulation, and thus the processing time is increased or the print time is increased. The development cost does not double when adding the function of the apparatus, and the print page management can be efficiently performed. Also, prepare front and back page information as page management information, refer to the front and back page information when restarting printing, and refer to the front and back page when the reprint start page is the back page. Convert the reprint start page to print from. Therefore, in the case of double-sided printing, when it is the reprint start page or the back page, it is possible to automatically convert it to the front page and start printing.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a page management system of a printing system of the present invention. Figure 1
In FIG. 1, 1 is print data stored in an information recording medium such as a magnetic disk, 2 is print data output means for extracting and outputting the print data 1 in predetermined block units, and 3 is transfer from print data output means 2. A printing device for editing and printing the print data of a predetermined block unit. Further, 4 is the page information obtained in the process of editing the print data of the printer 3, that is, the position in the block of the code that caused the page break and the page number of the page to which the print data after that code belongs. Is a page information transmission unit for acquiring the information of and returning it to the print data output unit 2. The page information transmission unit 4 acquires the page information each time the printing data is edited in a predetermined block unit by the printing device 3, and returns the page information to the print data output unit 2. The print data output means 2 checks the block position of the first block of the page based on the returned page information,
It is stored in the internal memory as page management information together with the page information. Reference numeral 5 denotes a print instructing unit for instructing printing, designating a printing page, and notifying that a failure has occurred in the printing apparatus 3.

Next, the operation of the above embodiment will be specifically described. First, when printing is instructed by the print instructing unit 5, the print data output unit 2 takes out print data of a predetermined block unit from the print data 1 and transfers it to the printing apparatus 3. The printing device 3 edits the print data of a predetermined block to create a print image, and prints. Here, when the print data is edited by the printing device 3, the page information transmission means 4 acquires the page information obtained in the process of the editing and returns it to the print data output means 2. That is, the print data output means 2 is notified of the position in the block of the code that has caused a page change in the process of editing and the page information of the page number of the page to which the print data after that code belongs. It The print data output means 2 checks the block position of the page top block based on the returned page information and stores it in the internal memory as page management information together with the previous page information. In this way, the print data output unit 2 takes in the print data 1 block by block in a predetermined block unit and sequentially transfers the blocks to the printing apparatus 3 block by block. Then, the printing device 3 edits and prints each block of the print data, and sequentially prints one page at a time.

If a failure occurs in the printing device 3,
When the printing is interrupted, the fact that the printing is interrupted is displayed on the display screen of the print instructing means 5 according to the instruction of the print data output means 2, and at the same time, the re-print start page is inquired. When the failure of the printing apparatus 3 is recovered and the printing apparatus 3 is ready for printing, and the user instructs the reprint start page by the print instruction unit 5, the print data output unit 2 first outputs the internal memory. The page management information stored in the table, that is, the page number, the block position of the first block of the page, the information of the position in the block of the code that caused the page change, etc. A process for checking the position of the first code on the print start page is performed. Of course, when restarting printing using another printing device 3,
In the print data output means 2, the position of the head code of the reprint start page is checked in exactly the same manner based on the page management information. The print data output means 2 sends the print data to the printing device 3 from the obtained code of the position, and the printing device 3 reprints from the print data of the designated reprint start page.

As described above, in this embodiment, the block position of the first block of the page is checked based on the page information obtained in the process of editing the print data by the printing device 3 for each predetermined block, and the preceding page is searched. When the printing apparatus 3 interrupts printing due to a failure or the like by storing it as page management information together with the page information, and then the failure is recovered and printing is restarted, it is specified based on the page management information. You can check the position of the first code on the reprint start page. Therefore, in order to obtain the position of the start code of the reprint start page specified based on the page information obtained when editing the print data instead of performing the print simulation, the print data becomes large and complicated. However, the processing time does not increase even if it is converted. Further, even if the function of the printing apparatus 3 is added, it is not necessary to add the equivalent function to the print simulation, so that the development cost does not double and the page management can be efficiently performed. .

Next, another embodiment of the present invention will be described. When reprinting a double-sided printed matter, if printing is started from a designated page or a print interruption page, printing may be performed from the back page. Therefore, in this embodiment, front and back information of a page is added to the above-mentioned page management information. More specifically, the print data output means 2 uses the page information returned from the page information transmission means 4 to determine the page number and its front / back information, the block position of the first block of the page, and the cause of the modified page. A correspondence table of the position of the code in the block is created and stored in the internal memory. Here, when the printing is restarted after the printing is interrupted due to a failure of the printing apparatus 3, the reprint start page designated by the print data output unit 2 with reference to the above-mentioned correspondence table is the back side. At this time, the printing device 3 is instructed to convert the front and back of the page so as to print from the front. Therefore, in this embodiment, when the reprint start page is the back page or the user mistakenly specifies the back page, the back page is automatically converted into the front page and printed. Therefore, you can always start printing from the front of the specified page, and you can solve the problem that printing is meaningless because printing is restarted from the back page as in the past. it can.

[0014]

As described above, according to the present invention, the position of the leading code of the reprint start page designated based on the page information obtained in the process of editing the print data by the printing device is checked and printed. By restarting, it is not necessary to check the position of the first block of the reprint start page by the print simulation as in the past, so the processing time does not increase even if the print data becomes large or becomes complicated,
You can manage pages efficiently. Further, since it is not necessary to perform a print simulation, it is not necessary to add a function equivalent to the print simulation even if a function is added to the printing apparatus, and the problem of increasing the development cost, which has been a conventional problem, is solved. can do. Further, by providing front and back information of the page as the page management information, when the reprint start page is the back page, it can be automatically converted into the front page and printed.
